METAL CAR.

SPECIFICATION forming part of Letters Patent No. 794,280, dated July 11, 1905.

Application filed March 31,1905. Serial No. 253,185.

To all whom 2325 may concern.-

Be itknown that I, CYRUS M. CARNAHAN, of Sandylake, in the county of Mercer and State of Pennsylvania, have invented a Metal Car, of which the following is a full, clear, and exact description, reference being had .to the accompanying drawings, forming part of this specification, in which Figure l is a side elevation of a part of the car. Fig. 2 is a plan view of a portion of the same, partially in section. Fig. 3 is an end view. Fig. 4: is a vertical cross-section on the line IV IV of Fig. 1.

My invention relates to metallic cars; and it has for its object the construction of a metal car from structural metal in such a manner as to obtain lightness and strength and the production of a car that may be used as a gondola or as a dumping-car, according to the character of the cargo to be carried.

In the drawings the frame of the car is shown composed of a series of vertical trusses A and D, which extend transversely in the body of the car in the form of a W, having vertical outer legs and horizontal channels B B. The trusses A are composed of angles 2 and 3 and the brace-plates 4, and they are riveted to the cross-plates O, which plates extend across the bottom of the car in a vertical position. The two outer channels B are riveted to the vertical angles 2 of the trusses car illustrated by the drawings there are supposed to be seven of these compound trusses; but of course this number will vary accordlng to the length of the car. The vertical plates O are of equal height, and as they extend across the car they form supports for the lumber or like cargo when the car is used as a gondola. The sides and floor of the car are composed of the plates F and G, which are riveted to the angles 3 and 5 of the compound trusses A and D. In the side plates F are doorways or openings, which are strengthened by the angle-pieces 6. These doorways are closed by the doors H, which are provided with strengthening angle-pieces 7 and are hinged to the car by any suitable means. The subtrusses E are composed of suitable angles, and they are placed between the main trusses D. The ends of the car are formed by the cross channels 8 and the plates 9. Longitudinal trusses are formed on each side of the car by the channels I and the channels B. On top of the sides of the car are channels 10. The space between the two channels B serves for the placement of the draftrigging. Instead of a body-bolster for the fifth-wheel of the car I employ two structural pieces 11, which are riveted to the bottom of the cross-plate of the trusses D, that are located at these positions on the car.

The trusses A and D may be formed and riveted together and kept in stock to be used in the manufacture of cars. The doors H may be located at desired points.

As the side plates of the car follow the line of the inner angles 3 of the trusses A, the doors swing inside of the frame of the car and are not liable toinjury. The arrangement of the floor-plates longitudinally and the location of the doors at the bottom of the angle and at the side of the car insure the complete delivery of the cargo when the doors are opened, and if the doors or any of them should be accidentally opened while the car is in motion the cargo will be delivered at the side of the car, where it can do no injury to the car or train.

The advantages of my invention result from the union of trusses to form the'frame of the car and the union of trusses, cross-plates, and trusses, which gives great strength and lightness, resulting in a greater carrying capacity.

Having thus described my invention, what I claim, and desire to secure by Letters Pat ent, is

1. Ina metal car, a series of vertical compound trusses, extending transversely, each compound truss consisting of inner pieces united in the form of a W, and outer vertical pieces united to and extending downwardly from the outer arms of the W, in combination with longitudinal bars and transverse vertical plates.

2. In a metal car, a series of vertical compound trusses extending transversely, each compound truss consisting of inner anglepieces united in theform of a W and outer vertical angle-pieces united to and extending downwardly from the outer arms of the W, in combination with longitudinal channels and side and bottom plates.

3. In a metal car, a series of vertical compound trusses extending transversely, each compound truss consisting of inner pieces united in the form of a W and outer vertical pieces united to and extending downwardly from the outer arms of the W, in combination with longitudinal bars, side and bottom plates and doors, arranged in the side of the car at the two lower apices of the trusses.

4. The combination of structural metal pieces forming a compound truss adapted to extend transversely in a metal car, each compound truss consisting of inner pieces united in the form of a W and outer vertical pieces united to and extending downwardly from the outer arms of the W.

5. In a metal car, a series of vertical compound trusses extending transversely, each compound truss consisting of inner pieces, united in the form of a W, and outer vertical pieces united to and extending downwardly from the outer arms of the W, in combination with longitudinal bars.

In testimony whereof I have hereunto set my hand.
